The schoolgirl had come home from visiting friends on Sunday night and had asked to watch a film in her room.

At around 9.30pm when Nyah was sleeping she noticed her tablets had gone missing.

"I noticed the packet had gone missing that night. I texted my partner to see if she knew where they were, but she had no idea. We thought I must have mislaid them.

"I knocked on Nyah's door at about 7am to wake her for school. She was laying on her bed on her side with her phone in her hand. I called her and I had no response so I walked towards her.

"I could see the tips of her fingers were blue, her lips were blue and her face was white so I screamed and screamed for my partner, Sue.

"We dialled 999 straight away.

"She knew how dangerous those tablets were. I just can't believe this has happened. She had so much to live for - she wanted to travel the world."

Paramedics put her into an ambulance and rushed her to hospital but Nyah's heart had already flatlined.

Dominique added: "They couldn't shock her heart as there was no rhythm. I knew then that she was gone."

The struggling mum-of-two said she didn't know if Nyah's school was aware how bad the situation was.

She said: "There was a mention when we were in a review meeting about some potential issues. Nyah felt a group of individuals were talking about her in class. To the extent she didn't want to be the first person to leave the room in case she drew attention to herself."

A spokesperson for Bishop Gore School said: "Everyone at Bishop Gore School has been deeply saddened to hear of the passing of Nyah James who was popular with both her fellow pupils and school staff.

"Nyah was achieving well and we were looking forward to her receiving excellent results at the end of year 11.

"Understandably since hearing of her passing, pupils and staff at the school are very upset and trained staff are on hand to support them.

"Our thoughts are very much with her family and friends at this very sad time."

Dominique said: "I just don't know what was going through her head. Teenagers shut you out. It's very rare you get to see into their life as they have their own little world - every day I told her I loved her.

"The bullying now has got 100x time worse - it's social media. Before, when I was a kid, you could come home and get away from the bullies. Now, the bullies are brought into the home so the child has nowhere to hide."
